k3 7536

Called V73NS tonite on 20 CW and he could not make out keying - said very choppy - the keying sounds fine in the headphones virtually no matter what I do. But on external rx it does in fact sound very choppy and sometimes misses characters ,

Using LOGIKIT CMOS4 external keyer - not the internal keyer.

Using
VOX
QSK SEMI
TX dly 020 (tx delay is also affecting CW weight)
CW QRQ is OFF

P3 is connected on the RS232 buss.

I turned off the logging computer - rebooted the K3 and still sounds lousy

If I use PTT with a foot pedal to PTT jack CW gets even more choppy

OK , what have I got set wrong ????

Re: k3 7536

Hank, can I suggest that you try the internal keyer, that will at least prove if it's the rig or your external keyer. I'd then start to look for RF feedback problems.

Hank, this is known problem. Set TX dly to default and see the result.

Re: k3 7536

You can probably get by with a TX Delay setting of 10 without noticing
any issues but 20 is definitely what is causing your problem.
